실험 절차

To a solution of (2S,4S)-1-Boc-4-amino[(dimethylamino)carbonyl]pyrrolidine (8 g, 31.5 mmol) prepared in Step C in toluene (100 ml) was added sodium t-butoxide (3.46 g, 36 mmol), 2-(di-t-butylphosphino)biphenyl (800 mg, 2.68 mmol), tris(dibenzylideneacetone)dipalladium(0) (1.6 g, 1.79 mmol) and 1-bromo-2,4-difluorobenzene (6.94 g, 36 mmol), and the solution was stirred at 110° C. for 10 h. After the reaction finished, the solution was filtered through Celite, and extracted with water and EtOAc. The organic layer was dried over MgSO4, concentrated in vacuo, and purified by column chromatography (eluent, EtOAc/Hex=1/4) to give the title compound (1.5 g, 78%).
